Atlantic Dark Quartzite

Atlantic Dark Quartzite is a unique and eye-catching natural stone, known for its dark, moody aesthetic. It is characterized by a deep forest-to-emerald green base with intricate interspersions of black, charcoal, and lighter grey-green mineral flecks. This stone is quarried in Guangxi, China and features a fine-to-medium granular or crystalline texture, offering a speckled, salt-and-pepper effect rather than the more fluid veining found in marbles. Its polished finish enhances its reflective qualities and reveals subtle shimmer within the quartz-rich minerals.

Physical and Mechanical Properties:

• Water Absorption: Typically low, generally around 0.10% - 0.30%.
• Density: Approximately 2,730 - 2,770 kg/m³.
• Flexural Strength: Ranges between 12 - 15 MPa, depending on the specific quarry and conditions.
• Compressive Strength: Typically high, often above 150 MPa.
• Hardness: Ranks between 6 and 7 on the Mohs scale, indicating good scratch resistance.
• Porosity: Generally low, correlating with its low water absorption rate.
• Slip Resistance: It varies with finish, though the polished surface may be less slip-resistant when wet.

Chemical and Mineral Composition (% by weight):

• Quartz: 70% - 90%
• Mica (Muscovite, Biotite): 5% - 15%
• Feldspar: 3% - 10%
• Minor Elements (Oxides, others): varies

Usage:

• Residential: Suitable for kitchen countertops, bathroom vanities, wall cladding, flooring, and decorative features.
• Commercial: Ideal for reception areas, office lobbies, upscale retail spaces, and feature walls.
• Exterior: Viable for outdoor cladding and facade work because of its durability and weather resistance.

Maintenance:

• General Cleaning: Use a pH-neutral cleaner to maintain its shine and avoid dullness over time.
• Sealing: Recommended to enhance its stain resistance.
• Avoid: Acidic or abrasive cleaners which can damage the polished surface.

Cutting Sizes (cm):

• Slabs: Commonly available in 2-3 cm thickness, with dimensions ranging from 240 x 120 cm to 300 x 180 cm.
• Tiles: Customizable but often in standard sizes like 30 x 30, 30 x 60, or 60 x 60 cm.

Surface Finish Options:

• Polished: High-gloss finish that enhances color and reflection.
• Honed: Smooth, matte finish that may offer better slip resistance.
• Leathered: Textured finish that provides a more rustic look with good grip.

Atlantic Dark Quartzite, with its combination of striking aesthetic and robust properties, is ideal for those seeking both beauty and durability in their natural stone installations.
